IMPROVEMENT IN MODES OF MAKING AXLE-CLIPS.

Specification forming part of Letters Patent No. 141,625, dated August 12, 1873; application filed March 3, 1873.

To all whom it may concern:

Be it known that I, HENRY M. BEEGHER, of Vest Meriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Forging Coach Axle-Clips, of which the following is a specification In the practice of my invention the metal is reduced my means of dies into the succession of forms hereinafter described.

In the accompanying drawings, Figure l is a plan view of the blank, which is the result of the first step in the process employed in the practice of my invention. Fig. 2 is a plan view of the blank, which is the result of the second step in said process. Fig. 3 is an edge view of theblank represented in Fig. 2. Fig. at is a plan view of a coach axleclip produced by my process. Fig. 5 is an edge view of the same. Fig. 6 is a front elevation of the blanking-die by means of which the blank, Fig. 1, is produced. Figs. 7 and 8 are right and leftside elevations of said die. Fig. 9 is a plan view of the bottom die employed to produce the blank shown in Figs. 2 and 3. Fig. 10 is a vertical section of said die and its follower taken on line as :10 of Fig. 3. Fig. 11 is a front profile of the trimmingdie. Fig. 12 is a plan view of the finishingdie, and Fig. 13 is a vertical section of said die and its follower taken on line 3 y of Fig.

I select stock of about the same thickness as the finished clip and of about the width of its widest portion, and by means of suitable dies, Figs. 6, 7, and 8, a portion of the bar is reduced and thrown into a blank of substantially the form shown in Fig. 1. The ends of this blank may vary somewhat in form so long as the narrow neck a, which is the essential feature of this blank,is retained.

, The blanking-dies A 13, Figs. 6, 7, and 8, may be used in any ordinary hammer or forging machine. They are so formedthat when their most prominent portions meet the space 0 will be of the proper depth to form the width of the neck a, while its thickness may be determined by the space (I, and the blank is cut from the bar by means of the cutters e 6. By placing the bar edgewise under the cutters to sever the blank, Fig. 1, the ends thereof will be properly beveled, as shown. I then subject this blank, Fig. 1, (after being first brought to a proper heat,) to pressure between dies 0 D,'Figs. 9 and 10, which are the counterparts of the form shown in Figs. 2 and 3, thus throwing the metal into said form.

In case any surplus metal (commonly termed a Win) is left at the edge of the blank,lremo've said fin by means of a cutting-die and punch, E F, Fig. 11, the contour of which die corresponds with that of the blank, as shown in Fig. 2, and the faces of which nearly correspond with an edge view of said blank, (see Fig. 3,) as is shown by the profile of said trimming-dies in Fig. 11. The blank, Figs. 2 and 3, is then subjected to pressure between dies G H g 9, Figs. 12 and 13, which dies are the counterparts of the form desired for the finished forged clip, thus throwing the metal into the form shown in Figs. 4 and 5, the same being a finished clip, so far as the forging is concerned.

For this last operation I prefer to employ folding-dies in which the lower die is made in three parts, H g g, the parts 1 g being made to close upon the part H simultaneously-with the follower G, substantially as shown in my patent of June 20, 1871, (machine for forming carriage-shackles,) whereby the blank, Figs. 2 and 3, may be farther bent by the last dies previous to the swaging action of said dies. If, however, solid dies are employed to complete the forging of the clip, the arms I) b of the blank, Figs. 2 and 3, should be bent up toward each other so as to be nearly parallel, and then swaged in the. dies, when the completed form will be the same as before described.

By my process I produce a superior article for a coach axle-clip, with full and square corners, and I produce it more economically than it can be produced by the method heretofore employed.

I claim as my invention--- The process herein described for forging coach axle-clips, which consists in reducing the metal in the manner described into the succession of forms herein set forth.
